| 2 | * Debugging Functions Source Code File |
| 3 | * |
| 4 | * $Id: debug.c,v 1.9 2002/04/22 03:39:43 mdharm Exp $ |
| 5 | * |
| 6 | * Current development and maintenance by: |
| 7 | * (c) 1999-2002 Matthew Dharm (mdharm-usb@one-eyed-alien.net) |
| 8 | * |
| 9 | * Developed with the assistance of: |
| 10 | * (c) 2002 Alan Stern <stern@rowland.org> |
| 11 | * |
| 12 | * Initial work by: |
| 13 | * (c) 1999 Michael Gee (michael@linuxspecific.com) |
| 14 | * |
| 15 | * This driver is based on the 'USB Mass Storage Class' document. This |
| 16 | * describes in detail the protocol used to communicate with such |
| 17 | * devices. Clearly, the designers had SCSI and ATAPI commands in |
| 18 | * mind when they created this document. The commands are all very |
| 19 | * similar to commands in the SCSI-II and ATAPI specifications. |
| 20 | * |
| 21 | * It is important to note that in a number of cases this class |
| 22 | * exhibits class-specific exemptions from the USB specification. |
| 23 | * Notably the usage of NAK, STALL and ACK differs from the norm, in |
| 24 | * that they are used to communicate wait, failed and OK on commands. |
| 25 | * |
| 26 | * Also, for certain devices, the interrupt endpoint is used to convey |
| 27 | * status of a command. |
| 28 | * |
| 29 | * Please see http://www.one-eyed-alien.net/~mdharm/linux-usb for more |
| 30 | * information about this driver. |
